Been fiddling trying to work out what does what and slowly but surely I'm heading in the right direction.
This is my latest using the DIY HCFR probe.
AE900E (NZ model)
Component at 576i(one day be able to upgrade to 720p)
Found measurements capable down to 10IRE, but to get the 00IRE to register I wound up the brightness by 4 clicks for the 00IRE then reset back to set point.
I have done some tests on a collector gain and had some progress, just needs fine tuning. But shows promise for the bottom end.
I spent a long time setting the RGB color and tint using the CIE REC601, once as close as possible I found the grey scale tracking twice as good from the start and saved alot of time endlessly running the grey scale.
Although I broke a number of rules, I tweaked overall contrast, color and tint all the time. Why?, because the gamma was clipping for a start, so had to back off contrast. The CIE points moved and so re-adjusted color and tint, a point here and there.
Blue is a little off on the CIE, but the probable reason is the blue shift in my painted screen,a white and lampblack grey. Think I got it under control, but a little oversaturated.
going to bed....2:16am tired but happy
